Specification of Letters Patent.

Patented June 30, 1914.

Application filed July 3, 1912. Serial No. 707,557.

To all whom it may concern Be it known that I, THOMAS SANroRn, a citizenof the United States, residing at Mount Braddock, in the county ofFayette and State of Pennsylvania, have invented a new and usefulTrolley-Pole and Trolley- Guard; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to a new and useful trolley pole and trolleyguard.

As one of the objects of the invention, it is the aim to provide animproved device of this nature having novel, desirable and practicalfeatures of construction.

A further object of the invention is the provision of an improvedtensioning means for the trolley pole, for holding the trolley wheelthereof frictionally against the wire.

A further object of the invention is to provide improved trolley guardmembers pivotally mounted one upon each side of the trolley head, forretaining the trolley wheel in engagement with the trolley wire.

A further object of the invention is the provision of means forautomatically closing the trolley guard members, when the pole is swungdownwardly on its pivot, and for holding the guard members closed, theautomatically actuating means for the guard members also acting to throwthe guard members open, when the trolley wheel is disengaged from thewire.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :F igure 1 is a view in elevation showing the improvedtrolley pole and trolley guard, as applied to the top of a car. Fig. 2is a perspective view of the trolley head with the trolley wheeltherein, showing the improved trolley guard members, and the means foroperating them. Fig. 3 is a sectional view on line 6-6 of Fig. 2. Fig. Ais a sectional view on line 7-7 of Fig. 3. Fig. 5 is a detail sectionalview showing a connection between the trolley head and the trolley pole.

Referring more particularly to the drawings l designates substantiallythe top of the car having a platform 2 thereon upon which is mounted tooscillatehorizontally a bracket between the arms of which is pivotallymounted a head 17 to which is secured the lower end of the trolley pole18. The trolley pole 18 is threaded in the base, there being a lock nut19 for rendering the trolley pole secure. Washers 20 are mounted betweenthe sides of the bracket and the base, thereby lessening the frictionalwear on the base 17. The upper end of the trolley pole termihates in asocket 23, in which an extension 24 of the trolley head 25 is threadedat 26, there being a lock nut 27 in order to render a secure joint.Mounted between the forks or sides 28, and upon the pin or shaft 29, isthe usual form of trolley wheel 30, which is adapted to frictionallycontact with the trolley wire 31. Pivotally mounted upon the bolts 32,which are carried by the downwardly extending sides 33 of the forks 28,and adjacent the sides 33 are plates 34-, to the lower ends of whichlaterally extending extension plates 35 are hinged at 36. The plates 34are provided with guide recesses 37, in which the spring blades 38 aredovetailed, the same being secured in said recesses by the bolts 32. Theupper ends of the spring blades are clove-tailed in the angled members40, which form trolley wire guards or aws, for retaining the wire in thegroove of the trolley wheel. Bolts or other suitable means 41 hold theupper ends of the blades dove-tailed as shown at 42 in the angularmembers 40. Connecting the extension plates 35 and the angular member40, by means of the eyes 43 and 44, are ropes or cables A5. Secured tounder face of the extension plates 35 adjacent their outer ends are eyes46, to which the cables or ropes 47 are connected. These ropes or cablesA7 form a junction 48 with the cable 49, which passes over the pulley50, mounted upon the pin 51 of the fork 52 of the arm 53. This arm 53 issecured at 54: between the cars 55 of the sleeves 56, which. is securedat 57 to the trolley pole 18. The arm 53 beyond the connection 54 isrectangular, as shown, and engages the collar between the ears 55, so asto prevent the arm from dropping to a vertical position. The end portion58 of the cable or rope 4:9 is secured to the eye 60 of the bracketmember 3. \Vhen the trolley pole is down in the position shown in Fig.l, and the trolley wheel is in engagement with the trolley wire, therope or cable 49 is loose,

and owing to the spring blades 38, the angled members 40 forming thetrolley guard are held closed, therebyacting to retain the 1 or guardsare held open against the action a of the spring blades 38, because thecable or rope 49 is drawn taut, owing to the fact that the distancebetween where the cables or ropes 4'7 connect to the eyes t6, and wherethe cable or rope 4&9 connects to the eyes 60 becomes greater.

The purpose for holding the guards open when the pole is in asubstantially vertical position is to obtain their open relations withone another, so that when the plate and the rope 67 are taken hold of atthe same time to pull the pole downwardly so as to engage the trolleywheel with the trolley wire, said open relations with said guards willbe maintained until the trolley wheel engages the wire. The tightness ofthe cable or rope 49, when the trolley pole assumes a substantiallyvertical position is assisted and increased by the provision of the arm53. Connecting to the eyes d4- are the ends of the cable 63, whichterminates in a loop 6a, which carries a plate 65. Connected to an eye66 of the trolley head is a rope or cable 67, which passes through anaperture 68 of the plate 65. When it is desired to disengage the trolleywheel from the trolley wire, a downward pulling action may be exertedupon the plate 65, which will throw the jaws or guards L0 outwardly,against the action of the spring blades, and then by pulling upon thecable or rope 67 at the same time, the trolley pole may be pulleddownwardly, and then by throwing the trolley head slightly to one sideof the trolley wire, the wheel 30 is disengaged from the trolley wire.The head 25 is provided with eyes 70, between which and the eyes 44springs 71 are connected, which are placed slightly under tension whenthe trolley guards are opened.

Extending through the trolley head is a bolt 72, upon which a U-shapedmember 73 is pivotally mounted, the upper forward portion of whichterminates in forks 74. Formed between the forks 7 a is a groove 75,which receives the trolley wire 31, and constitutes means for scrapingor cutting the ice or sleet from the wire.

In the drawings there is disclosed a certain structure, but in practicalfields this structure may necessitate alterations, to which the patenteeis entitled, provided the alterations are comprehended within the scopeof what is claimed.

From the foregoing it is to be noted there has been devised a novel andessentially new and improved trolley pole connection and trolley guard,and one which has been found particularly desirable and practical.

The invention having been set forth, what is claimed as new and usefulis 1. In combination with a trolley head having, a downwardly extendingloop portion, plates pivotally bolted to the outer faces of the sides ofthe loop portion, a pair of angular arms designed to close over thetrolley wire, resilient connections between the angular arms and saidplates, laterally extending arms hingedly connected to the lower end ofsaid plates, connections between the lateral arms and the angular arms,means connected to the lateral arm designed to exert downward pull onthe lateral arms when the pole of the head moves toward a Verticalposition, to throw the angular arms apart against the resilientconnection, means connected to the angular arms to pull thereon to holdthem separated when lowering the pole, and a trolley wheel carried bysaid head.

2. In combination with a trolley pole head having a downwardly extendingloop portion, a trolley wheel mounted in the head, a pair of platespivotally bolted to the outer faces of the sides of the loop portion, apair of laterally extending arms hinged to the lower ends of saidplates, a pair of angular arms designed to close over the trolley wheeland wire constituting trolley guards to retain the wire in engagementwith the wheel when the trolley pole is down, resilient leaf bladesconnecting said angular arms to the upper portions of said platesexerting a normal pressure to hold the angular arms closed over thetrolley wire, connections between the angular arms and the outer ends ofthe lat-eral arms, means connected to the outer ends of the lateral armsdesigned to pull thereon where by the angular arms are thrust apart whenthe trolley pole is thrown toward a vertical position, and meansconnected to the angular arms for holding them separated when loweringthe trolley pole, I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
